CROSS REFERENCE TO RELATED PATENT APPLICATIONS

This application claims priority in part to U.S. patent application Ser. No. 61/049,761 filed May 1, 2008 entitled “Container For Eyedrop Solution” by Thomas J. Contreras of Winfield, Ill.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to dispensing containers, and more specifically to a dispensing container having a retention clip or ring for ease of carrying.

2. Description of Related Art

The use of eyedrops is a necessity for many individuals. Individuals with dry eye syndrome, environmentally irritated eyes, wearers of contact lenses, patients with eye diseases or other conditions which require the use of over-the-counter or prescription ophthalmic pharmaceutical preparations and others, oftentimes require convenient and frequent access to eyedrops or other eye care solutions. Containers for eyedrops can fall from pockets, be misplaced, tip or spill, or otherwise be inaccessible when needed. Women will often carry eyedrops in their purse. However, men do not have a convenient place to carry eyedrops other than their shirt or pants pockets. In addition, many women today do not wish to carry purses at all times. Eye care solution containers that are commonly sold today do not have a convenient way to be carried on one's person.

Thus, there exists an unmet need for an eye care solution container that can be conveniently carried without the risk of loss, leakage or misplacement. It is thus an object of the present invention to provide an eye care solution container that will not fall from one's pocket. It is another object of the present invention to provide an eye care solution container that will be convenient and comfortable to carry. It is another object of the present invention to provide an eye care solution container that will not become inverted or tip and leak in one's pocket. It is a further object of the present invention to provide an eye care solution container that is aesthetically pleasing and ergonomically shaped.

BRIEF SUMMARY OF THE INVENTION

In accordance with the present invention, there is provided an eye care solution container with retention device comprising a generally hollow body for holding eye care solution, the body having a top and a bottom, a nozzle attached to the top of the body for dispensing the eye care solution, a cap that is removably attached to the body and that covers the nozzle, and a clip having a first end and a second end, the first end of the clip being attached to the cap, and the second end of the clip having a protrusion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

For a general understanding of the present invention, reference is made to the drawings. In the drawings, like reference numerals have been used throughout to designate identical elements.

The present invention and the various embodiments depicted, described and envisioned herein provide an improved container for holding and dispensing a liquid. The container includes a body for holding a liquid such as eyedrop solution or contact lens solution, and has a dispensing opening for dispensing the solution, and a cap with retention device for selectively exposing the dispensing opening for use. The retention device may be a clip or a ring, as further described herein. Additionally, there is a current trend toward utilizing plastic products that are biodegradable and otherwise more compatible with ecological processes once the application for their use has been completed. Currently there are no eye care solution containers made from compostable plastics or from a 100% renewable resource such as corn. In some embodiments of the present invention the eye care solution container, with a retention device, or without, is made from a compostable 100% renewable resource such as corn.

Turning now to FIG. 1, a perspective view of the eye care solution container with retention device 100 is depicted. A hollow body 101 is depicted that holds a liquid such as, for example, eye care solution. The hollow body 101, in one embodiment, is generally cylindrical. In some embodiments of the present invention, the body may contain marks or etchings of graduation marks. In FIG. 1, the hollow body 101 is shown with a cap 103 attached. The cap 103, as will be depicted and described by way of FIGS. 7 and 9, covers a nozzle and is hollow with internal threads (not shown in FIG. 1, see FIG. 9). Attached to the cap is a clip having a first end and a second end, the first end of the clip being attached to the cap 103 and the second end of the clip having a protrusion. The eye care solution container with retention device 100 is shown with a flat bottom 107. The bottom of the body 101 may have other geometries. The flat bottom 107 allows the device to stand upright when placed on a flat surface.

FIG. 2 is a plan view of the eye care solution container of FIG. 1 showing a flat bottom 107.

FIG. 3 is a plan view of the eye care solution container with retention device having a rounded bottom. The bottom of the body 301 has a rounded bottom 303. Such a rounded bottom may be for aesthetic reasons, but also may allow the device to slip freely into a pocket and clipped.

FIG. 4 shows a bottom view of the eye care solution container with retention device where the bottom 401 can be seen along with the clip 105.

FIG. 5 is a top view of the eye care solution container with retention device where the cap 103 and the clip 105 can be seen, the clip 105 being attached to the cap 103. The clip 105 may be molded or otherwise made from the same material as the cap 103, or the clip 105 may be attached to the cap 103 using various mechanical fastening techniques such as gluing, stapling, riveting, press fitting, or the like. The clip 105 may also be made from a plastic or may be made from a metal.

FIG. 6 is a plan view of the eye care solution container with retention device showing the body 101, cap 103, and attached clip 105.

Turning now to FIG. 7, a partially exploded view of the eye care solution container with retention device is shown. The body 101 has a neck with external threads 701 such that the cap 103 may be screwed onto the neck and thereby become attached to the body 101. The external threads on the neck 701 may be made from the same material as the body 101, or may be fastened or otherwise attached to the body 101. The body 101 holds an amount of liquid, for example, eyedrops, in an amount such as 5 milliliter, 8 milliliter, 15 milliliter, 30 milliliter or other such quantity. The body 101 is made from a plastic such as High Density Polyethylene (HDPE), and may be made from a conventional mold, or by blow, fill, and seal methodology or other techniques known to those skilled in the art. The body may be, in one embodiment of the present invention, about 45 millimeters long and about 13.3 milliliters in diameter. Other body sizes may also be used. When the cap 103 is attached to the body 101, the overall length may be, for example, about 7 to 8 centimeters. The cap 103 contains internal threads, as can be seen in FIG. 9. The cap 103 and clip 105 may, in one embodiment of the present invention, be made in one piece using, for example, an injection molding process that incorporates a plastic such as, for example, polypropylene (PP). Also shown in FIG. 7 is a nozzle 703 for dispensing a solution such as eye care solution in a drop by drop manner. The nozzle 703 can formed in a unitary fashion with the body 101 (such as by way of blow fill and seal methodology), or can be made separately and fit or inserted (as in a snap-in dropper tip nozzle) into the neck 701 (such as is currently utilized with conventional eye drop bottles) and thereby attached to the body 101. The cap 103 may also optionally contain a puncture mechanism, such as a molded pin, to open the end of the nozzle 703 for dispensing. This puncture mechanism is necessary for dispensing when an aseptic blow fill and seal method is utilized for fabrication or manufacturing. Also shown in FIG. 7 is an insert 705. The insert 705 can be used in some embodiments of the present invention to ensure that a predetermined drop size is released from the nozzle 703. In addition, various sized nozzles (snap in dropper tip inserts, or blow molded nozzles or inserts 705) may be available to allow one to dispense a specified quantity of droplet solution, as prescribed by a doctor, for example. The snap-in dropper tip, or nozzle 703 allows for the creation of volumetric drop sizes when the body 101 is squeezed or otherwise deformed. Examples of drop sizes include 30 microliter, 40 microliter, 50 microliter, 60 microliter, and the like.

Turning now to FIG. 8, a plan view of the cap of the eye care solution container with retention device is depicted. The cap 103 is shown with a clip 105 and a protrusion 801. The clip 105 is attached to the cap 103 at a first end and contains a protrusion 801 at a second end. The protrusion 801 serves to retain the device on a pocket or other fabric structure when in use. The clip 105 may have a length greater than the length of the cap 103 such that the clip 105 overlies the body 101, as can be seen in FIG. 6. The body may also have geometries other than cylindrical. For example, the body could be square and so designed to utilize a retention clip in an acceptable manner (i.e. with a small axle system that allows the retention clip to remain stationary when the cap is twisted onto the bottle).

FIG. 9 is a cutaway view of the cap of FIG. 8. Shown are the internal threads 901 for mating with the external threads 701 of the device as depicted in FIG. 7. Also shown in FIG. 9 is a cap insert 903 that is made from a plastic and serves to retain the nozzle 703 (see FIG. 7) and prevent leaks from occurring. When the cap 103 is securely screwed onto the body 101, the cap insert 903 allows the nozzle 703 to be securely positioned such that liquid cannot be dispensed from the device when the cap is in place and the device is not in use. The cap insert 903 may be molded along with the cap 103 or may be a separate piece. In some embodiments of the present invention, the cap insert may also have various geometries or may be eliminated entirely.

It should be noted that the eye care solution container with retention device may be made from a plastic such as high density polyethylene, polypropylene, and the like, or the device may be made from a plant based plastic such as a plastic polylactide or polylactic acid resin. Such an environmentally friendly or “green” eye care solution container may gain widespread interest based on its compostable qualities, and because of manufacture from a 100% renewable resource. It is another embodiment of this invention to manufacture eye care solution containers, with or without, a retention device, from compostable 100% renewable resources such as corn based polylactic acid resin or from tapioca, for example, or other plant based sources of compostable plastics.

To use the present invention, the eye care solution container with retention device is inserted into a pocket such as a shirt pocket with the fabric of the shirt pocket placed between the cap and the clip. In this way, the eye care solution container with retention device is securely attached to a pocket, ready for use. To use the eye care solution container with retention device, the device is removed from one's pocket, the cap is unscrewed, and drops are placed in the eye by way of squeezing the body of the device while the device is tipped and the nozzle is placed above the eye. After drops are dispensed, the cap is reattached to the body by way of screwing the cap to the body.

In another embodiment of the present invention, and as depicted in the perspective view in FIG. 10, the clip 105 may be replaced with a ring 1003 that is attached to, or molded with, a cap 1001. The cap 1001 contains internal threads similar to those depicted in FIG. 9. The cap 1001 and ring 1003 may, in one embodiment of the present invention, be made in one piece using, for example, an injection molding process that incorporates a plastic such as, for example, polypropylene (PP). It should be noted that the eye care solution container with retention device may also be made from a plastic such as high density polyethylene, polypropylene, and the like, or the device may be made from a plant based plastic such as a plastic polylactide. The ring 1003 may also be made from a plastic, a metal such as steel, stainless steel, brass, or the like. The ring 1003, in one embodiment of the present invention, may contain a split to allow for convenient placement on a key ring or the like. Other structures similar to a split ring arrangement, such as a hinge, staggered split rings, a split ring pin and socket, and the like, may also be used to provide for convenient placement and use.

FIG. 11 depicts a plan view of the cap of FIG. 10, and FIG. 12 shows a perspective view of the cap and ring assembly in place on an eye dropper body 101.

To use the cap and ring embodiment of the present invention, the eye care solution container with retention device is attached to a key ring, zipper pull, or similar structure by mechanically opening the ring and placing it through the key ring, zipper pull, or similar structure. In this way, the eye care solution container with retention device is securely attached to a key ring, zipper pull, or similar structure, and ready for use. To use the eye care solution container with retention device, the device is removed from the key ring, zipper pull, or similar structure by opening the ring and removing it, the cap is unscrewed, and drops are placed in the eye by way of squeezing the body of the device while the device is tipped and the nozzle is placed above the eye. After drops are dispensed, the cap is reattached to the body by way of screwing the cap to the body, and the device may then be reattached to the key ring, zipper pull, or other structure.

In another embodiment of the present invention, a cap and clip structure is disclosed that can be attached to an existing bottle of liquid such as a bottle of eye care solution or a unit dose package. FIG. 13A depicts such a cap and clip structure where an attachment cap 1301 has attached a clip 1303. The attachment cap 1301 and clip 1303 may, in one embodiment of the present invention, be made in one piece using, for example, an injection molding process that incorporates a plastic such as, for example, polypropylene (PP). The cap and clip structure may be made from a plastic such as high density polyethylene, polypropylene, and the like, or the device may be made from a plant based plastic such as a plastic polylactide. The clip 1303 may, in some embodiments of the present invention, be attached to the attachment cap 1301 with a ball and socket or a pin and socket setup, as can be seen in FIG. 13D. Such an arrangement allows for the eye care solution cap to rotate independent of the clip 1303, allowing for unobstructed closing and opening of the eye care solution bottle. The attachment cap 1301 is generally hollow, and may take on various geometries to better conform to specific liquid bottles and eye care solution containers. On the interior of the attachment cap 1301 is placed an adhesive 1305 that allows for attachment of the cap and clip structure to an existing cap from a liquid bottle such as an eye care solution container. The cap and clip structure is placed over an existing cap and pressed into place. Once the adhesive 1305 is properly set, the droplet container will now have a clip and can now be used. FIG. 13B shows a perspective view of the attachment cap and clip structure, FIG. 13C shows a plan view of the attachment cap and clip structure, FIG. 13D shows a top view of the attachment cap and clip structure, and FIG. 13E shows a bottom view of the attachment cap and clip structure. To use the present invention, the resulting eye care solution container with retention device is inserted into a pocket such as a shirt pocket with the fabric of the shirt pocket placed between the cap and the clip. In this way, the eye care solution container with retention device is securely attached to a pocket, ready for use. To use the eye care solution container with retention device, the device is removed from one's pocket, the cap is unscrewed, and drops are placed in the eye by way of squeezing the body of the device while the device is tipped and the nozzle is placed above the eye. After drops are dispensed, the cap is reattached to the body by way of screwing the cap to the body.

In another embodiment of the present invention, a cap and ring structure is disclosed that can be attached to an existing bottle of liquid such as a bottle of eye care solution or a unit dose package. FIG. 14A depicts such a cap and ring structure where an attachment cap 1401 has attached a ring 1403. The attachment cap 1401 and ring 1403 may, in one embodiment of the present invention, be made in one piece using, for example, an injection molding process that incorporates a plastic such as, for example, polypropylene (PP). The cap and ring structure may be made from a plastic such as high density polyethylene, polypropylene, and the like, or the device may be made from a plant based plastic such as a plastic polylactide. The ring 1403 may, in some embodiments of the present invention, be attached to the attachment cap 1401 with a ball and socket or a pin and socket setup, as can be seen in FIG. 14D. Such an arrangement allows for the eye care solution cap to rotate independent of the ring 1403, allowing for unobstructed closing and opening of the eye care solution bottle. The attachment cap 1401 is generally hollow, and may take on various geometries to better conform to specific liquid bottles and eye care solution containers. On the interior of the attachment cap 1401 is placed an adhesive 1405 that allows for attachment of the cap and ring structure to an existing cap from a liquid bottle such as an eye care solution container. The cap and ring structure is placed over an existing cap and pressed into place. Once the adhesive 1405 is properly set, the droplet container will now have a ring and can now be used. FIG. 14B shows a perspective view of the attachment cap and ring structure, FIG. 14C shows a plan view of the attachment cap and ring structure, FIG. 14D shows a top view of the attachment cap and ring structure, and FIG. 14E shows a bottom view of the attachment cap and ring structure. To use the resulting attachment cap and ring embodiment of the present invention, the eye care solution container with retention device is attached to a key ring, zipper pull, or similar structure by mechanically opening the ring and placing it through the key ring, zipper pull, or similar structure. In this way, the eye care solution container with retention device is securely attached to a key ring, zipper pull, or similar structure, and ready for use. To use the eye care solution container with retention device, the device is removed from the key ring, zipper pull, or similar structure by opening the ring and removing it, the cap is unscrewed, and drops are placed in the eye by way of squeezing the body of the device while the device is tipped and the nozzle is placed above the eye. After drops are dispensed, the cap is reattached to the body by way of screwing the cap to the body, and the device may then be reattached to the key ring, zipper pull, or other structure.

In another embodiment of the present invention, and as depicted in FIGS. 15A-15E, a unit dose body 1501 is provided with a ring 1505. FIG. 15A is a plan view of the device, FIG. 15B is a perspective view of the device, FIG. 15C is a side view of the device, FIG. 15D is a top view of the device, and FIG. 15E is a bottom view of the device. As seen in FIG. 15A, the unit dose body 1501 has a removable top 1503 upon which the ring 1505 is attached or otherwise molded. In some embodiments of the present invention, the ring 1505 may also be attached to the unit dose body 1501. A unit dose package for dispensing a liquid such as eye care solution is a small hollow envelope like structure that is commonly made of a plastic such as High Density Polyethylene (HDPE), and may be made by blow molding, for example. The unit dose package may also be made from a plant based plastic such as a plastic polylactide. A unit dose package commonly has a removable tear off top that, when removed, exposes a small opening to dispense the solution contained within the unit dose package. Often, the removable top is reattachable, making the unit dose package disposable but usable for a day or two. There is, thus, utility in incorporating a unit dose applicator for eye care solutions with a retention device (such as a clip or a ring). The ring 1505 may be molded in one piece including the unit dose body 1501 and unit dose top 1503. The ring 1505 may also be made from a plastic, a metal such as steel, stainless steel, brass, or the like. The ring 1505, in one embodiment of the present invention, may contain a split to allow for convenient placement on a key ring or the like. The ring 1505 may be a separate piece attached with adhesive after the initial manufacturing of the unit dose container, molded with the unit dose container, or otherwise attached in production or by the end user. Other structures similar to a split ring arrangement, such as a hinge, staggered split rings, a split ring pin and socket, and the like, may also be used to provide for convenient placement and use.

To use the unit dose ring embodiment of the present invention, the device is attached to a key ring, zipper pull, or similar structure by mechanically opening the ring and placing it through the key ring, zipper pull, or similar structure. In this way, the eye care solution container with retention device is securely attached to a key ring, zipper pull, or similar structure, and ready for use. To use the eye care solution container with retention device, either the ring is removed from the key ring, zipper pull, or similar device, or the unit dose top is removed with the ring attached, and drops are placed in the eye by way of squeezing the unit dose body of the device while the device is tipped and the unit dose nozzle is placed above the eye.

In another embodiment of the present invention, and as depicted in FIGS. 16A-16E, a unit dose body 1601 is provided with a clip 1605. FIG. 16A is a plan view of the device, FIG. 16B is a perspective view of the device, FIG. 16C is a side view of the device, FIG. 16D is a top view of the device, and FIG. 16E is a bottom view of the device. As seen in FIG. 16A, the unit dose body 1601 has a removable top 1603 upon which the clip 1605 is attached or otherwise molded. In some embodiments of the present invention, the clip 1605 is attached to the unit dose body 1601 and top 1603. A unit dose package for dispensing a liquid such as eye care solution is a small hollow envelope like structure that is commonly made of a plastic such as High Density Polyethylene (HDPE), and may be made by blow molding, for example. The unit dose package may also be made from a plant based plastic such as a plastic polylactide. A unit dose package commonly has a removable tear off top that, when removed, exposes a small opening to dispense the solution contained within the unit dose package. Oftentimes, the removable top is reattachable, making the unit dose package disposable but usable for a day or two. There is, thus, utility in incorporating a unit dose applicator for eye care solutions with a retention device (such as a clip or a ring). The clip 1605 may be molded in one piece including the unit dose body 1601 and unit dose top 1603. The clip 1605 may also be made from a plastic, a metal such as steel, stainless steel, brass, or the like. The clip 1605 may be a separate piece incorporated into a structure that fits over the cap 1603 of a standard unit dose body and cap, attached with adhesive after the initial manufacturing of the unit dose container, molded with the unit dose container, or attached in production or by the end user. The clip 1605 may further have a protrusion at one end to ensure that the device is properly retained in a pocket or the like.

To use the unit dose clip embodiment of the present invention, the unit dose clip device is inserted into a pocket such as a shirt pocket with the fabric of the shirt pocket placed between the unit dose body/top and the clip. In this way, the device is securely attached to a pocket, ready for use. To use the unit dose clip device, the device is removed from one's pocket, the unit dose top is torn off or otherwise removed, and drops are placed in the eye by way of squeezing the body of the device while the device is tipped and the unit dose nozzle is placed above the eye. Once the eye care solution (in this case an eye drop) has been dispensed, the top can be replaced, and now with a retention device, it can be secured in a stable location until it is used again.

It is, therefore, apparent that there has been provided, in accordance with the various objects of the present invention, an eye care solution container with retention device. While the various objects of this invention have been described in conjunction with preferred embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art.
